■When riding in an aircraft
When bringing a key with wireless
remote control function onto an air-
craft, make sure y ou do not press
any buttons on the key while inside
the aircraft cabin. If you are carrying
the key in your bag etc., ensure that
the buttons are not likely to be
pressed accidentally. Pressing a
button may cause the key to emit
radio waves that could interfere with
the operation of the aircraft.
■Key battery depletion
●The standard battery life is 1 to 2
years.
●If the battery becomes low, an
alarm will sound in the cabin and a
message will be dis played on the
multi-information display when the
hybrid system stops.
●To reduce key battery depletion
when the electronic key is to not
be used for long periods of time,
set the electronic key to the bat-
tery-saving mode. ( P.166)
●As the electronic key always
receives radio waves, the battery
will become depleted even if the
electronic key is not used. The fol-
lowing symptoms indicate that the
electronic key battery may be
depleted. Replace the battery
when necessary.
• The smart key system or the wire-
less remote contro l does not oper-
ate.
• The detection area becomes
smaller.
• The LED indicator on the key sur- face does not turn on.
You can replace the battery by your-
self ( P.447). However, as there is
a danger that the electronic key may
be damaged, it is recommended
that replacement is carried out by
your Toyota dealer.
●To avoid serious deterioration, do
not leave the electronic key within
3 ft. (1 m) of the following electri-
cal appliances that produce a
magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Table lamps
• Induction cookers
●If the electronic key is near the
vehicle for longer than necessary,
even if the smart key system is not
used, the key battery may become
depleted faster than normal.
When not using the smart key sys-
tem, it is recommended not to stay
with the electronic key near the
vehicle longer than necessary.

■Confirmation of the registered
key number
The number of keys already regis-
tered to the vehicle can be con-
firmed. Ask your Toyota dealer for
details.
■If “A New Key has been Regis-
tered Contact Your Dealer for
Details” is displayed on the
multi-information display
This message will be displayed
each time the driver’s door is
opened when the doors are
unlocked from the outside for
approximately 10 days after a new
electronic key has been registered.
If this message is displayed but you
have not had a new electronic key
registered, ask your Toyota dealer
to check if an unknown electronic
key (other than those in your pos-
session) has been registered.
NOTICE
■To prevent key damage
●Do not drop the keys, subject
them to strong shocks or bend
them.
●Do not expose the keys to high
temperatures for long periods of
time.
●Do not get the keys wet or wash

materials.
●Do not disassemble the keys.
●Do not attach a s ticker or any-
thing else to the surface of the
keys.
●Do not place the keys near
objects that produce magnetic
fields, such as TVs, audio sys-
tems and induction cookers.
●Do not place the keys near
medical electrical equipment
such as low-frequency therapy
equipment or microwave ther-
apy equipment, and do not
receive medical attention with
the keys on your person.
■Carrying the electronic key
on your person
Carry the electronic key 3.9 in.
